Sunsu Katsu is a tonkatsu restaurant in Dangsan-dong, across from the Yeongdeungpo-gu Office, serving rosu katsu, hire katsu, and cheese katsu. The thick cutlets come with wasabi, salt, curry, and tonkatsu sauce, and rice, soup, and side dishes can be refilled. Each seat has a hair tie, and the hire katsu is served with salad, jangguk, myeonginanmul, and kkakdugi. At lunch, group reservations fill the seats quickly, so without a booking the food takes a while to arrive.
